"High Performance Buildings, properly planned, do not cost more than traditional buildings"

Fact: Contractors across the USA have been building High Performance Buildings at the same cost or less, in most building types.

Heating, Ventilation, and Air Conditioning (HVAC) is the technology of  indoor environmental quality.  The goal is to provide  thermal comfort and acceptable indoor air quality.  HVAC system design is a sub-discipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer.  Refrigeration is sometimes added to the field's abbreviation as HVAC&R or HVACR.  Ventilation (the V in HVAC) is the process of exchanging or replacing air in any space to provide high indoor air quality which involves temperature control, oxygen replenishment, and removal of moisture, odors, smoke, heat, dust, airborne bacteria, carbon dioxide, and other gases.  Ventilation removes unpleasant smells and excessive moisture, introduces outside air, keeps interior building air circulating, and prevents stagnation of the interior air.  Ventilation includes both the exchange of air to the outside as well as circulation of air within the building.  It is one of the most important factors for maintaining acceptable indoor air quality in High Performance Buildings.  A Complete definition of HVAC should be reviewed by contractors, as research shows approximately 50% of homeowners are not happy with their indoor environments.


HVAC Load Calculations and System Oversizing - Why The Big Deal?
If you have a building that is 3X or more energy efficient, HVAC designers cannot design and install systems as they do in conventional buildings, and expect the comfort, efficiency and performance to follow

                   HVAC & Radiant Floor Design,
Initial Investment in Value - Accurate Sizing,
Lifetime of Comfort & Savings

Radiant does not have comfort compromises like Forced Air Systems,
that include temperature stratification, drafts, cool floors, building
pressurization that increases leakage, the sound of forced air delivery
and dust movement within ducting and living spaces.

Air to Air Cold Climate Heat Pumps

Air to Air Heat Pumps

HVAC System Cold Climate Heat Pumps offer a wide assortment of options... with mini split systems utilizing indoor mounts for wall, floor, ceiling and concealed duct, and also Cold Climate Heat Pumps for Central Air Duel Fuel Systems.  Be sure to have your HVAC system designer includes the best and most energy efficient available, giving you the choice to use gas or heat pump heating down to cold temps.

Cold Climate Heat Pumps are one of the best places to start for cooling and back up heating in a quality Radiant Floor Heat System.  They are also good for Central Air Systems, as a primary heating and cooling system, using a condensing gas furnace for extreme conditions or as back up heating with a backup generator.  

Our designs use packages of energy efficient components from major manufactures utilizing Condensing Gas Furnaces (96% or more) and Cold Climate Heat Pumps with outstanding performance down to -22F.

Cold Climate Mini Split Heat Pumps with ratings up to 38 SEER
Cold Climate Central Heat Pumps with ratings up to 20 SEER


Designs for Heat Pumps for Air Cooling for Radiant Projects and Back Up Heat to -22 F
Concealed Duct or Central Air Heat Pumps are sometimes best for multiple rooms.

Power and Lineset can be Roughed-in and Finished with a Heat Pump at a later Date

Hydronic Radiant Based HVAC Systems


Hydronic Radiant Based HVAC System Components
Radiant does not have comfort compromises like Forced Air Systems,
that include temperature stratification, drafts, cool floors, building pressurization that increases leakage, the sound of forced air delivery and dust movement within ducting and living spaces. 

HVAC Load Calculations are an important part of every design.  All materials used and positioned correctly is a common error in DIY hydronic design and installation, often leading to complicated problems with a system.  Several sources for DIY Hydronics are here for your convenience, just remember your local expert; friend, plumber, HVAC and maybe your concrete finisher may not be the best source.

Boilers - Water Heaters

Conventional Boilers have long been used for heating radiant floor heat systems for a variety of reasons (high temp requirements), but primarily because low temperature water heating devices and heat emitters were not commonly available in the industry, again for a number of reasons (cast iron, condensation and corrosion may come to mind).  The trend continues to this day with many unaware of advances in heating devices, specialty materials and High Performance Building Products.

High Performance Residential Hydronic HVAC systems that we design have no ferrous (corrosive) elements in the system.  The water temperature requirements are typically 85F or less for heating.  With that requirement, we have successfully for decades used several different water heating systems to include Electric, Gas (NG or LP), Solar Thermal, Wood Heaters and Heat Pumps (hydronic cooling), but not a conventional boiler.  Currently Gas heaters are the most cost effective with solar thermal coming in as the next best value.  Options abound...
